LUBRICATING DEVICE FOR WINDMILLS.

Application filed October 24;, 1922.

To alZ whom it may concern:

Be it known that I, ORED OLssoN, a citizen of the United States and a resident of 0rd, in the county of Valley and State of Nebraska have invented a new and Improved Lubricating Device for Windmills,

of which the following is a full, clear, and

exact description.

This invention has relation to windmills l0 and has particular reference to a lubricating device therefor.

The invention contemplates for its principal object a device for automatically conveying tothe moving elements of a windmill lubricant in order to minimize friction and wear on the parts.

As a further object the invention contemplates an automatic lubricating system for windmills which obviates the necessity of having to frequently climb to the top of the windmill supporting structure for the purpose of manually lubricating the various bearings and moving parts.

The invention furthermore contemplates a lubricating system for windmills which is extremely simple in its construction and does not materially increase the -cost of manufacture, and which is thoroughly reliable and highly efiicient in its purpose.

lVith the above recited and other objects in view, the invention resides in the novel construction set forth in the following specification, particularly pointed out in the appended claims and illustrated in the accompanying drawings, it being understood that the right is reserved to embodiments other than those actually illustrated herein to the full extent indicated by the general meaning A of the terms in which the claims are ex pressed.

In the drawings Figurel is a fragmentary plan view of the upper portion of a windmill with the propeller wheel removed.

Fig. 6 is a fragmentary sectional View taken approximately on the line 6-6 of Fig. 5. V

Fig. 7 is a fragmentary front view of the driven gear, parts being shown in section to disclose the underlying structure.

Fig. 8 is a face View of'the dustproof packing plate or disk.

Fig. 9 is a face view of the upper end of the pitman.

Referring to the drawings by characters of reference, 10 designates a housing or casing which is supported from the upper end of the windmill frame structure which is provided with a tubular bearing 11 extending therethrough and projecting from one side of the casing, said bearing being provided at itsouter end with an anti-friction roller bearing 12. The windmill driving shaft 13 extends through the tubular bearing sleeve 11 and is provided at its inner end with a drive pinion 14L keyed thereto. A driven year 15 is mounted on a countershaft 16 supported by the tubular bearing 17 provided in the housing; The driven gear 15 is provided with an eccentric crank pin 18 which extends through and connects with the pitman head 19 which is in turn connected with and reciproca-tes the pump rod (not shown). The countershaft 16 has secured thereto a sprocket 20 directly beneath which an oil hopper 21 is disposed. A second sprocket 22 is mounted on a stub shaft 23 in the lower portion of the housing or casing 10 and said sprockets are operatively connected by a sprocket chain 24 which causes simultaneously driving of the sprocket 22 with the sprocket 20 when the countershaft is rotated with the driven igeari 15. The lower end of the housing or casing 10 constitutes a reservoir or container for a supply of lubricating oil in which the lower sprocket 22 and the sprocket chain 24 are partially submerged. The oil hopper 21 is'provided with outlet openings 25 and 26, the former outlet being disposed in vertical alignment with a subterposed aperture 27 in the tubular bearing 11 whereby a portion of the oil which is conveyed by the chain and dropped into the oil hopper 21 is fed therefrom through the outlet 25 to the tubular bearing '11 through the aperture 27 .1 The opposite outlet opening 26 of the oil hopper 21 is disposed immediately above an inclined conduit 28 which is in the nature of a flange formed on the side of a web 29 provided on the tubular bearing 11. The drive pinion 14 is arranged within an oil box 30 over which the lower end of the conduit 28 is disposed for conveying and supplying oil to the oil box 30' from the oil hopper, 21.

The oil which is fed through the apertur 27 to the tubular bearing 11 is conveyed by the same to the roller bearing 12 for lubricating saidroller hearing. The propeller wheelis provided with a rotary bearing collar 31 which is mounted between the annular beads 32 on the tubular bearing and said rotary bearing collar is lubricated by a wick 33 which passes throughuthe aperture 34 in the side of the tubular bearing-11 said wick conveying the oil by saturation from the interior ofthe tubular bearing to an oil groove 35 in theinner periphery of the collar 31'. A sliding sleeve 36 mounted for movement on the tubular bearing is lubr1- cated by a wick 37 which is passed through the: aperture 38: inthe side of the tubular bearing and feeds oil to the inner periphery of the sleeve A rotary ring 39 mounted in the annular groove 40 of the sliding sleeve s lubricated through t e aperture 41 in said sleeve which conveys the oil to the inner peripheral groove 42 oat the ring 39. In order tov convey the lubricant to the crank pin18, the driven gear is provided with oil passages 43 in its periphery on opposite moles of: one of the teeth, said oil passages terminating ina common passage 44 which is incl'inedv downwardly to. discharge directly onto the crank pin. A loose ring'45 is arranged on; the crank pin and confined between the confronting faces of the driven gear 15 and the pitmanv head 19;.4 A drain plate 4;6is carried by the pitman head and is provided at the inner end with a down-- turnedspeut 47: whereby superfluous oil or lubricant is. returned by means of the spout from the crank pin to the oil box, said spout emptying into; an oil conveying space 48% definedbyi the plate49= secured to the inner side of one of the walls of the housing or casing 10. In order to. render the interior oat. the casing or housing 10; dust, dirt and moisture-mocha disk 50 having a facing 51 is impinged against the side of the housing supported. from thegdriven gear 15 by means of spring pressed bolt 52. The up:- per open end: o-fthe housing or casing 10 is closedzby acovering hood 53 which alsoeX- 11 tends over and partly embraces the pitman he aid; 19,:

linuse and. operation oi the invention,-the

lower end ofthev casing or; housing 10. is

filled with a supply of oil or other lubricant whereby the same constitutes a reservoir. When the driye shaft is'rotated; by the propeller wheel the countersliatt 16 will be simultaneously rotated through the interengagement of the meshing drive 1 and driven gears 14 and 15 thus operating the sprockets 20 and22 and the sprocket chain 24-. which will lift and feed the oil or lubricant from the reservoir to the hopper 21. From this point the oil will be discharged respectively through the apertures 25 and 26 From the aperture 25 the oil will flow into the aperture 27 between the guard strip 54 and the side of the housing or casing. This will introduce oil to the interior of the tubular bearing 11 where it will feed the wicks 33 and 37 and the roller bearing 12, thus lubricating the rotary bearing collar 31 for the angular bracing spokes of the: propeller wheelfiandthe main bearing for the drive shaft as well. as the sliding sleeve 36 and the ring '39. The lower periphery of the tubular bearing 11 isprovided with a discharge opening 54 which permits the lubricant in excess of the amount needed to return" into the bottom of the casing or housing 10 from the hollow sleeve. From the aperture. 26 the oil will flow through. the conduit 28 to the oil boX 30 from whence it will be conveyed? from. the gear teeth ofthe gear 14 to the gear teethof thegewr 15. When the portion 0% the gear 15- whieh is provided with the oil passages 43' arrives at the top of its cycle of moyement, the oil on the periphery will flow through the passages 43 to. the common passage 44 where it will flow onto the crank pin. ring 45 will spread the oil and effect proper lubrication between the crank pin and the bearing opening in the pitman head 19. Superfluous oil trom the crank pin will be caught by the drain plate 46 of the pitman head and returned through the downturned spout 47 to the oil conveying space 48 defined between the plate 49 and the side wall- The loose of the housing or casing back to the. oil box.

Should the oil box 30- overflow the. superflu ous oilthereifirom. will drain directlyback into the bottom of the hOLlSiIlg; or casing 1 which constitutes the initial reservoir. 1n event that the feed hopper 21 is, overfed, the oil; will likewise drain back into the bottom ofthe housing or casing.
